The 2008 project consisted of a Haussmannian-style balcony attached to a boom-truck that allowed it to be quickly fitted and removed from French buildings. The Balcon Additionnel could not be separated from its boom-truck base, and was merely placed close to a series of different architecture facades in order to be photographed, and not actually attached for use.

But could this plastic add-on balcony become a viable architectural extension? Check out the images below.
